Abstract

Expansive wave absorption system for military and armored vehicles consisting of the construction of the body and interior of the vehicle through an internal pre-structure of hollow frames available to boxes, (Fig. 1) with a considerable thickness and once these are closed boxes with the inner shield, are injected inside these boxes or hollows, synthetic rubber of the elastomer type. (Fig. 2 / a), in order to form an expansive wave absorption system that mitigates the lethal effects of explosive wave propagation.

Description

Shock wave absorption system for military and armored vehicles.

TECHNICAL SECTOR

This invention corresponds to the technical sector of the military and defense sector.

STATE OF THE TECHNIQUE

Most armored combat vehicles are manufactured with welded steel alloy plates,

or more rarely due to its cost, formed in one piece, and in some cases aluminum or other light alloys such as synthetic fibers.

As armor, armored transport generally uses steel or aluminum, which is sufficient as protection against small arms and most shrapnel. However, this armor is insufficient for most anti-tank weapons.

The cars are not protected by an armor of uniform thickness, but the thickness depends on the probability of receiving an impact in each zone.

Over time it has become common to use composite shields with which to avoid the entry of projectiles or jets of gas and metal

incandescent hollow charge pumps. In addition, the use of ceramic materials placed between metal plates has become common.

The lower part and the roof have little protection, of varying thickness but in any case a few centimeters, which is clearly insufficient to counteract any type of anti-tank weapons.

A new form of armor, was to place packages of explosives covering the helmet in the most important points of the sheet. If a projectile hits one of those blocks, both will explode. But the explosion of the tank block will tend to render the perforating or hollow loads of the projectile useless, so the armor will not be affected.

On the other hand, it is said that in explosive devices named "low explosives" the shock wave is approximately 1000 meters / sec and in explosive devices named "high explosives" is approximately 7000 meters / sec.

The shock wave is a sharp rise in the atmospheric pressure produced by the release of energy that takes place in the pump. Upon penetrating the body, the shock wave subjects the body viscera to a high overpressure and violent displacement. This also causes the breakage of the surface of dense materials, such as the gastrointestinal wall or the alveolar wall.

In addition, from the damage caused to such surfaces, the blood vessels that water these organs burst, causing serious internal bleeding. On the other hand, the passage of the shock wave causes the tissues to move at different speeds according to their density, which causes severe damage.

It is necessary and is the objective of this patent, a system of absorption of shock waves that mitigates the lethal effects on the personnel of these military and armored vehicles.

DETAILED DESCRIPTION OF THE INVENTION

This shock absorption system consists of the construction of the body and interior of the vehicle by means of an internal pre-structure of hollow frames available to boxes, (Fig. 1) with a considerable thickness and once these boxes are closed with the inner shield , it is injected inside these boxes or hollows, synthetic rubber of the elastomer type. (Fig. 2 / a).

Rubber is widely used in the manufacture of tires, tires, waterproof and insulating articles, due to its excellent elasticity and resistance properties to acids and alkaline substances. It is water repellent, insulating temperature and electricity.

Synthetic rubber is a type of elastomer, a polymer. An elastomer is a material with the mechanical property of being able to suffer much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation.

It is also a good heatsink of explosive waves, in addition to being able to dissipate the heat of explosive deflagration, thus preventing and attenuating the so-called "blast syndrome" which is the set of lesions

produced as a result of the propagation of the explosive wave generated by an explosive focus through the

organism.

EXHIBITION OF AN EMBODIMENT

One way of manufacturing this shock wave absorption system is the construction of the

5 body and interior of the vehicle, by means of an internal pre-frame structure for the function of creating holes available for boxes, (Fig. 1) with a considerable thickness and once these boxes are closed with the inner armor, synthetic rubber is injected from the type elastomer inside these boxes or holes so that it absorbs the blast waves of the explosion (Fig. 2 / a).
